CurrencyFreaks is a REST API providing real-time and historical foreign exchange rates for 166 fiat currencies, 4 precious metals, and 850 cryptocurrencies, with data sourced from forex exchanges, cryptocurrency exchanges, and national banks dating back to 1984. It suits developers building currency conversion, financial reporting, or multi-currency pricing features, with a free tier capped at 1,000 requests per month and USD base currency only. Paid plans start at $9.99 per month and unlock additional base currencies, conversion endpoints, time series, and update frequencies as fast as 60 seconds. SDKs are available in nine languages, and customers include HP, Gartner, and Equiti.

Scores are computed deterministically from this profile's published, sourced fields (pricing, compliance, capabilities, docs and developer-surface signals) - not from reviews or paid placement. Each axis is 0-100; an unknown signal scores 0 for that axis. Procurement ease is the inverse of buying friction (higher = easier to adopt).
